Product Description:

The MHD115C-058-NG0-AN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It carries size code 115 with length code C and is used in drive systems that require closed-loop rotary motion for positioning, indexing, and coordinated multi-axis operation. Relative position feedback from an internal optical measuring system allows the controller to execute repeatable moves after referencing, which is useful in automated machining cells, packaging lines, and similar production equipment.

At standstill, the motor supplies a continuous torque of 70.0 Nm, allowing it to support demanding loads without overheating. A flange diameter of 192 mm works with a centering diameter of 180 mm to position the housing accurately during mounting, and the power lead exits on side A through an output connector for straightforward cable routing. Internal channels provide liquid cooling, which removes heat more effectively than surface convection and helps maintain torque in compact cabinets. The IP65 enclosure resists dust and water jets, and the digital servo feedback (HSF) encoder sends high-resolution rotor data to the drive. Winding code 058 identifies the electrical setup for this motor, while the plain shaft supports straightforward coupling alignment.

System precision reaches ± 0.5 angular minutes, helping the axis maintain tight positioning tolerances once the feedback system has been referenced. Class F insulation supports winding temperatures up to 155 °C, and a shaft seal helps limit oil intrusion at the output end. The motor tolerates storage temperatures from -20 to +80 °C, and installation is permitted up to 1000 m above sea level before derating may be necessary. It is supplied without a holding brake, so any stationary load must be secured by the machine or by drive-generated holding torque.
